They are a more "tricky" team. They are about controlling and manipulating the opponent. It is more difficult to do that if you don't have a foundation in the game. You can always try it out, but masons or brewers are a easier learning team.

I think this thread had some good information.
I've watched one game and loved the mobility from Midas and the new plays. If you're a fishermen player you may like them or all the conditions might drive you nuts.

From the Steamforged newsletter. Kind of sounds like the puppet can use replication.
WHO SHOULD RECRUIT THE MASTER PUPPETEER & HIS PUPPET?
Are you a veteran Mortician coach looking to increase your goal threat? Then Brainpan & Memory are the players you've been waiting for!
Their dynamic playstyle will not only help you control the ball more but the puppet can also dish out terrifying pain—field the pair with Graves for more bloodshed or Bonesaw for total ball domination.
To maximize the strategic potential of your Morticians rosters and play even more mind games with your opponents, be sure to recruit this dynamic, creepy duo!

I have an issue with Tenderiser. I have a hard time justifying a model with the 1 Inf generation on a team where it feels like every Inf must carry more work. Exceptions being the berserk players. It's probably just me though.

Rather disappointed. Setting Seenah gave me hope that they would get the tweaks they needed. Minx was a big buff but was a buff to everyone who would use her almost more than for hunters because of the access to snare to the other teams. I will keep trying to make it work. I know some players have success with hunters but maybe aren't my style.
